Bug description: Joining key returns as blank when key is used in OUT LEFT
JOIN
Description:
------------
If you do an OUTER LEFT JOIN and set PDO FetchALL to PDO::FETCH_ASSOC, any
primary keys you used in the OUTER LEFT JOIN will be set to a blank if
there are no records returned in the JOIN.
If we are joining using a field called "product_id" from a product table
to an image table using an outer left join, and no records exist for that
"product_id" in the image table, the product id comes back as blank in the
resulting array
Reproduce code:
---------------
//query the product table and join to the image table and return any
images, if we have any, for each product. Assume the image table contains
no records
$sql = "SELECT * FROM product, image
LEFT OUTER JOIN image ON (product.product_id = image.product_id)";
$array = $stmt->fetchAll(PDO::FETCH_ASSOC);
print_r($array);
?>
Expected result:
----------------
Array
(
[0] => Array
(
[product_id] => 16
[notes] => "this product..."
[brand] => "Best Yet"
...
Actual result:
--------------
Array
(
[0] => Array
(
[product_id] =>
[notes] => "this product..."
[brand] => "Best Yet"
...
